Description

节目推荐方法、 终端设备及网络系统 技术领域
本发明涉及通信技术领域， 特别涉及一种节目推荐方法、 终端设备及网 络系统。
背景技术
现在交互式网络电视 IPTV业务和通信业务融合， 产生一些增值业务， 比如好友电视。 好友电视是指正在观看 IPTV 电视节目的用户通过网络来邀 请其他用户一起观看电视节目的一种增值业务， 好友电视不仅仅用在 IPTV 中， 也可以用在 PC、 移动终端的 TV业务中。
当用户 （推荐方） 向好友（被推荐方）推荐一个节目时， 用户所在的终 端将推荐消息发送给好友所在的终端， 推荐消息包括该节目的 ID， 好友所在 的终端根据该节目的 ID， 向媒体服务器发送播放请求， 媒体服务器将节目流 下发给好友所在的终端。
现有技术具有如下缺点：
现有技术中好友所在的终端接收媒体服务器下发的节目流， 只能将节目 流从头到尾播放给好友， 好友也只能从头到尾的观看被推存的节目， 导致用 户体验不高。

101、被推荐方所在的终端接收推荐方所在的终端发送的推荐消息， 所述 推荐消息包括： 节目标识和推荐方推荐的部分节目流的标识；
102、根据所述节目标识和部分节目流的标识， 发送用于指示媒体服务器 下发所述节目的部分节目流的指示消息；
103、 接收所述媒体服务器下发的所述部分节目流。
其中， 上述指示消息可以包括后续实施例二中的会话协商请求消息， 该 会话协商请求消息仅包含部分节目流传输通道信息。
其中， 节目标识可以是节目的地址信息。
本发明实施例一中的被推荐方所在的终端根据接收的部分节目流的标 识， 指示媒体服务器仅下发部分节目流， 可以实现推荐部分节目流的目的， 同时由于只需要媒体服务器下发部分节目流， 可以节省网络带宽等资源。
实施例二：
参阅图 2， 本发明实施例二提供一种节目推荐方法， 该方法包括：
201、 推荐方所在的机顶盒（Set Top Box, STB )接收推荐方输入的推荐 请求， 向推荐方提供推荐操作界面。
该步骤可以适用于如下场景， 推荐方觉得某个电影的原声非常好， 可以 做听力教材， 打算推荐给某个好友（被推荐方）， 推荐方可以通过遥控器选择 菜单中的 "推荐" 按钮， 此时， 推荐方所在的 STB接收到推荐方的推荐请求， 然后显示推荐操作界面。
202、 推荐方所在的 STB接收推荐方在操作界面输入的推荐条件， 并接收 被推荐方信息， 其中， 推荐条件包括： 部分节目流推荐指示信息。
续上述实例， 推荐方在推荐操作界面中的下拉菜单中选择 "只推荐音频" 条目， 并通过好友列表选择推荐对象（即上述被推荐方）， 此时， 推荐方所在 的 STB接收到 "只推荐音频" 这个推荐条件， 并接收到被推荐方的信息。
其中， 推荐方也可以手动在推荐操作界面中输入推荐条件， 不影响本发 明的实现。
203、推荐方所在的 STB根据上述部分节目流推荐指示信息和当前节目的 标识， 生成超连接， 该超链接的形式可如下所示：
IPTV://CoDServer/movie 1 /ep22?streamID=audio 1；
其中 IPTV://CoDServer/moviel/ep22部分为节目的点播地址， audio 1为音频 流标识， ？ streamID=audio 1标识只推荐音频流。
204、推荐方所在的 STB将携带该超链接的推荐消息发送给被推荐方所在 的 STB，其中，上述推荐消息可以是会话初始协议（ Session Initiation Protocol， SIP ) 消息， SIP消息的格式可以如下：
MESSAGE sip:xiaoxue@domain.com SIP/2.0

From: sip:Potian@domain.com;tag=49583
To: sip :xiaoxue@domain. com
Call-ID: asd88asd77a@l.2.3.4
CSeq: 1 MESSAGE
Content-Type: text/plain； application-type: content sharing
Content-Length: 50
IPTV://CoDServer/movie l/ep22? streamID=audio 1
该步骤中的推荐消息也可以不采用 SIP消息， 而采用其他消息， 比如短消 息 （Short Messaging Service, SMS ), 不影响本发明的实现。
205、被推荐方所在的 STB接收到推荐消息后，向被推荐方提示推荐消息。 比如可以向被推荐方提示 "你的好友 **向你推荐一个节目的部分媒体流（比 如音频流）， 是否接收？ "， 被推荐方所在的 STB接收到被推荐方对上述提示 的确认信息。
206、 被推荐方所在的 STB根据推荐消息， 向 SCF ( Service Control Function, 业务控制功能）发起只包含音频流传输通道信息的会话协商请求消
207、 SCF将该会话协商请求消息发送给媒体服务器（Media Function, MF )。
208、 MF收到会话协商请求消息后， 向 SCF发送会话协商响应消息。
209、 SCF向被推荐方所在的 STB发送会话协商响应消息。
210、 被推荐方所在的 STB向 MF发送播放请求。
211、 媒体服务器下发该部分节目流给被推荐方所在的 STB， 被推荐方所 在的 STB播放该部分节目流。
其中， 该实施例中推荐方也可以指定该部分节目流的具体时间段， 此时 步骤 202中推荐方所在的 STB也就接收到推荐方输入的时间范围指示信息， 相 应的， 步骤 203中生成的超链接中会包括时间范围指示信息， 在步骤 211中媒 体服务器就下发该时间范围内的部分媒体流， 比如该时间范围内的音频流。
本发明实施例二中推荐方所在的 STB将部分节目流标识发送给被推荐方 所在的 STB， 被推荐方所在的 STB仅需与媒体服务器对部分节目流进行协商， 接收媒体服务器下发的部分节目流， 以实现推荐部分节目流的目的， 同时由 于只需要媒体服务器下发部分节目流， 可以节省网络带宽等资源。
实施例三：

402、 推荐方所在的 STB接收推荐方在所述操作界面输入的推荐条件， 并 接收被推荐方信息， 其中， 推荐条件包括： 部分画面推荐指示信息、 部分画 面范围指示信息、 时间范围指示信息和部分画面展示方式指示信息。
续上述实例， 推荐方所在的 STB接收推荐方在所述操作界面输入的推荐 条件可以采用如下方式进行，如推荐方以推荐操作界面中的下拉菜单的形式， 比如在下拉菜单中选择 "只推荐部分画面" 条目， 并在推荐操作界面中的子 菜单中选择部分画面范围， 假定推荐操作界面中的子菜单提供 "左下角 1/3屏 幕、 右下角 1/3屏幕、 左上角 1/3屏幕、 右上角 1/3屏幕" 等选项， 推荐方在多 个选项中选择一个（比如左下角 1/3屏幕）， 并在推荐操作界面中的子菜单中 选择部分画面展示方式， 假定推荐操作界面中的子菜单提供 "高亮突出显示"
"高亮度圏显示" 等选项， 推荐方选择一种展示方式（比如高亮突出显示）。 推荐方并在操作界面中的子菜单中输入时间范围 "10分钟 ~ 12分钟"， 并通过 好友列表选择推荐对象（被推荐方）， 此时， 推荐方所在的 STB接收推荐方在 所述操作界面输入的部分画面推荐指示信息、 部分画面范围指示信息（部分 画面范围为左下角 1/3屏幕）、 时间范围指示信息 （时间范围为 10分钟 ~ 12分 钟）和部分画面展示方式指示信息（部分画面以高亮突出方式显示）。
其中， 提供部分画面展示方式选项的子菜单中还可以包括慢放和快放选 项， 推荐方可以选择慢放选项， 使后续被推荐方所在的终端慢速播放该时间 段内的节目流， 以便被推荐方注意上述穿帮镜头。 息和部分画面范围指示信息， 生成可缩放矢量图形（Scalable Vector Graphics,
SVG )代码， 并根据时间范围指示信息和 SVG代码， 生成超连接， 该超链接 的形式可以采用如下所示：
IPTV://CoDServer/moviel/ep22? begin=" 10:00"&end=n 11 :00" & SVG=".."; 其中， IPTV://CoDServer/moviel/ep22部分为节目的点播地址；
begin="10:00"&end="12:00"标识只推荐第 10分钟 ~ 12分钟；
SVG="..."表示该节目的部分画面的范围及该部分画面的展示方式信 息。
404、推荐方所在的 STB将携带该超链接的推荐消息发送给被推荐方所 在的 STB, 其中， 该推荐消息可以是 SIP消息， SIP消息的格式可以如下： MESSAGE sip:xiaoxue@domain.com SIP/2.0 Via: SIP/2.0/TCP Potianpc.domain.com;branch=z9hG4bK776sgdkse Max-Forwards: 70

Content-Type: text/plain； application-type: content sharing
Content-Length: 50
IPTV://CoDServer/movie l/ep22? begin="10:00"&end=" 12:00" & SVG="..."
405、被推荐方所在的 STB接收到推荐消息后，向被推荐方提示推荐消息。 比如可以向被推荐方提示 "你的好友 **向你推荐一个节目， 是否接收？ ，， 并 将消息中的 SVG=" ... "部分保存， 被推荐方所在的 STB接收到被推荐方对上述 提示的确认操作。
406、 被推荐方所在的 STB根据推荐消息， 向 SCF发起包含节目流传输通 道信息的会话协商请求消息。
